In the sixth chapter, according to our nations situations, a probing study on the development and application of natural mordenite was carried out at the aim to develop a new adsorbent carrier and reduce the cost of adsorbent preparation. The characters of natural mordenite were chemically changed by an acid. The effects of the acid solution concentration, temperature, mordenite size and treatment times on the physico-chemical characters of mordenite were undertaken. The adsorption equilibrium of CO on the character-changed natural mordenite was measured.

objective:to make a comparative analysis of the total saponins content in polygalaceae phloem and xylem parts to guide clinical treatment.methods:we determined the polygalaceae total saponins content at the 575 nm with oleanolic acid as a reference substance and vanillin-perchoric acid as a developer by using uv-visible spectrophotometry.results:the total saponins content of xylem parts was 3.33%,and that of polygalaceae phloem was 0.69%.conclusion:the total saponins content in polygalaceae xylem parts is much more than that of phloem parts,the total saponins in polygalaceae mainly exists in xylem parts.

目的：对远志原药材木部及皮部中总皂苷含量进行比较分析，用以指导临床用药。方法：以齐墩果酸为对照品，香草醛－高氯酸为显色剂，采用紫外－可见分光光度法在575 nm处测定远志总皂苷含量。结果：以此方法对远志木部及皮部中总皂苷含量进行比较、分析，为远志皮部总皂苷含量为3.33 %、木部总皂苷含量为0.69 %。结论：远志中皮部总皂苷含量远远大于木部，远志总皂苷主要存在于根皮中。

The serum selenium is first digested by microwave treatment and then chemically purified before analysis by using sulphydryl cotton. The optimum conditions were found to b as follows:(1) The sulphydryl cotton column is prewashed with 5 mol/L hydrochloric acid;(2) Se is desorbed by adding 1 mL of concentrated nitric acid and (3) the optimum amount of sulphydryl cotton is 0.14 g. This preconcentration step is required in order to remove matrix-interfering elements, such as Na, Mg, K and Ca.
